Open the CIPO recordAbstract From the Canadian patent
The invention describes a system and a method to separate ions (and charged particles) suspended in gas based on their ion electrical mobility. Most common ion mobility analyzers involve two parallel plate (or concentric cylinder) elements (electrodes) (200 and 210 in Fig. 2) between which is imposed an electrical field perpendicular to a sheath gas flow field between the cylinders. Separation occurs because high mobility ions tend to follow the electric field while low mobility ions tend to follow the flow field (260 and 280 in Fig. 2). This invention describes various configurations of electrical elements and sheath gas flow fields for ion mobility separation devices with unique …

Why it's free to use
- Filed February 21, 2004 and granted July 10, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 21, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 21, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
